Overview

The AD5700/AD5700-1 are single-chip solutions, designedand specified to operate as a HART® FSK half-duplex modem,complying with the HART physical layer requirements. TheAD5700/AD5700-1 integrate all of the necessary filtering, signaldetection, modulating, demodulating and signal generationfunctions, thus requiring few external components. The 0.5%precision internal oscillator on the AD5700-1 greatly reducesthe board space requirements, making it ideal for line-poweredapplications in both master and slave configurations. The maximumsupply current consumption is 115µA, making  theAD5700/AD5700-1 an optimal choice for low power loop-powered applications.Transmit waveforms are phase continuous 1200 Hz and2200 Hz sinusoids. The AD5700/AD5700-1 contain accuratecarrier detect circuitry and use a standard UART interface.
